[0003] The hydroponic device for zonal cultivation of plant roots includes a cultivation rack and a hydroponic box. The cultivation rack can place the hydroponic box at a suitable height for easy daily operation and management. The interior of the hydroponic box is divided into different zones, and the environmental parameters of each zone can be precisely controlled. At different growth stages of the plant, such as the seedling stage, a lower concentration of nutrient solution and a higher humidity environment may be required, while during the flowering and fruiting stage, the composition of the nutrient solution and pH level need to be adjusted. By independently controlling these parameters of each zone, the hydroponic box creates a specific and optimal growth environment for the plant roots.

[0004] Traditional cultivation racks are mostly fixed in size. In practical applications, when users need to increase the number of hydroponic plants, they often need to purchase new hydroponic devices because the cultivation racks cannot be flexibly expanded. This not only takes up more space but also increases costs. Therefore, a hydroponic device for zonal cultivation of plant roots is proposed to solve the above-mentioned problems.

A horizontal plate is fixedly installed between the two movable plates.

[0008] The top support frame includes a top bracket fixedly installed on the top of the connecting plate. Two top fixing plates are fixedly installed on the left outer surface of the top bracket. Movable plates are slidably installed inside the two top fixing plates. A top connecting frame is fixedly installed between the left sides of the two movable plates.

[0009] Preferably, the bottom of the top connecting frame is fixedly connected to the top of the horizontal plate.

[0010] Preferably, the two bottom fixing plates, connecting plates, and fixing brackets are integrated into one unit, and the two moving plates, connecting frames, and cross plates are integrated into one unit.

[0011] The top bracket and the two top fixing plates are integrated into one unit, as are the two movable plates and the top connecting frame.

[0012] Preferably, the bottom support frame and the top bracket are respectively installed with limiting components. Each of the two limiting components includes a fixing rod fixedly installed inside the two bottom fixing plates and the top fixing plate. One end of each of the two bottom fixing plates and the top fixing plate is provided with a movable hole. The surfaces of the two movable plates and the moving plates are fixedly installed with protruding teeth. The interior of each of the two bottom fixing plates and the top fixing plate is provided with two mounting cavities. The inner walls of the eight mounting cavities are rotatably mounted with rotating shafts. The inner walls of the eight mounting cavities are fixedly mounted with return springs.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. This hydroponic device for zonal cultivation of plant roots features an extendable bottom and top support frame, allowing for expansion of horizontal space as needed. When the number of garden plants increases or agricultural production temporarily expands, there is no need to purchase a new set; the support frame can be extended to increase the number of cultivation boxes, fully utilizing both vertical and horizontal space and effectively solving the problem of limited space utilization. Furthermore, the layout of the cultivation boxes can be flexibly adjusted according to the different growth requirements of various plants.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The hydroponic device for zonal cultivation of plant roots in this embodiment includes a bottom support frame 1, a top support frame 2, two culture boxes 3 and a one-way valve 4. The top support frame 2 is fixedly installed on the top of the bottom support frame 1. Culture boxes 3 are respectively installed on the top of the bottom support frame 1 and the top support frame 2. One-way valves 4 are installed on the left and right sides of the two culture boxes 3.

[0027] It should be noted that the hydroponic device for zonal cultivation of plant roots consists of a bottom support frame 1, a top support frame 2, two culture boxes 3, a one-way valve 4, and a limiting component 5. The hydroponic device is designed with two layers, with the bottom culture box 3 having two independent cavities inside. Both culture boxes 3 are made of transparent acrylic sheets, while the bottom support frame 1 and the top support frame 2 are made of anodized aluminum alloy profiles.

[0028] The bottom support frame 1 includes two bottom fixed plates 101 located inside the bottom support frame 1. A connecting plate 102 is fixedly installed between the right sides of the two bottom fixed plates 101. A fixed bracket 103 is fixedly installed between the bottoms of the two bottom fixed plates 101 and located at the bottom of the connecting plate 102. A movable plate 104 is slidably installed inside each of the two bottom fixed plates 101. A connecting frame 105 is fixedly installed between the bottoms of the two movable plates 104. A horizontal plate 106 is fixedly installed between the two movable plates 104.

[0029] The top support frame 2 includes a top bracket 201 fixedly installed on the top of the connecting plate 102. Two top fixing plates 202 are fixedly installed on the left outer surface of the top bracket 201. Movable plates 203 are slidably installed inside the two top fixing plates 202. A top connecting frame 204 is fixedly installed between the left sides of the two movable plates 203.

[0030] Limiting components 5 are installed inside the bottom support frame 1 and the top support frame 2 respectively. Each limiting component 5 includes a fixing rod 501 fixedly installed inside the two bottom fixing plates 101 and the top fixing plate 202. A movable hole 502 is opened at one end of each of the two bottom fixing plates 101 and the top fixing plate 202. A tooth 503 is fixedly installed on the surface of each of the two movable plates 203 and the moving plate 104. Two mounting cavities 504 are opened inside each of the two bottom fixing plates 101 and the top fixing plate 202. A rotating shaft 505 is rotatably installed on the inner wall of each of the eight mounting cavities 504. A return spring 506 is fixedly installed on the inner wall of each of the eight mounting cavities 504. A limiting block 508 is fixedly installed on the outer surface of each of the eight rotating shafts 505.

[0031] Specifically, when extension is required, the bottom support frame 1 extends by sliding the movable plate 104 inside the bottom fixed plate 101. When space needs to be expanded, the connecting frame 105 can be pushed to drive the two movable plates 104 to slide inside the bottom fixed plate 101, thereby changing the position of the horizontal plate 106 and achieving the effect of extending the bottom support frame 1 in the horizontal direction. Since the bottom of the top connecting frame 204 is fixedly connected to the top of the horizontal plate 106, when the bottom support frame 1 extends, it also drives the two movable plates 203 to slide inside the top fixed plate 202.

[0032] Specifically, the fixing rod 501 in the limiting assembly 5 is installed inside the bottom fixing plate 101 and the top fixing plate 202, providing a track and limiting for the sliding of the movable plate 203 and the moving plate 104, so that they can only move within the range defined by the fixing rod 501, ensuring the stability and accuracy of the support frame during the extension and retraction process.

[0033] Meanwhile, the protruding teeth 503 on the surfaces of the movable plate 203 and the moving plate 104 cooperate with the limiting block 508. When the movable plate 203 and the moving plate 104 slide to the appropriate position, the limiting block 508 is engaged with the tooth groove in the protruding teeth 503 under the action of the return spring 506, fixing the movable plate 203 and the moving plate 104 in the current position and preventing them from sliding at will due to external forces or other factors. This ensures that the incubator 3 can remain stable after placement and will not shake or fall due to the movement of the support frame, thus ensuring the safety and reliability of the hydroponic device.

[0034] Specifically, by setting the bottom support frame 1 and the top support frame 2 as extendable support frames, the problem of limited space utilization is solved. In actual use, whether it is home gardening with an increase in the number of plants or agricultural production temporarily expanding the planting scale, the number of cultivation boxes 3 can be increased by extending the support frames, making full use of vertical and horizontal space, without having to purchase the entire set of equipment again, avoiding taking up too much extra space. Secondly, it improves the flexibility of the device. Unlike the space requirements for plant growth, the extendable support frames can flexibly adjust the layout of the cultivation boxes 3 according to the actual growth status of the plants.

[0035] In this embodiment, a physical isolation layer, independent nutrient solution delivery pipes, gas exchange micropores, and sensors are simultaneously set in the incubator 3, which can create independent salinity and water microenvironments for the root system of different regions of the plant. For example, in the root system of a single plant, heterogeneous stress between the upper and lower layers and left and right partition control in the lower layer can be achieved. This is of great significance for studying the growth response of plants under different environmental conditions and optimizing the plant growth environment. By precisely controlling the environmental parameters of each region, the special environmental needs of plants at different growth stages can be met, thereby improving the growth quality and yield of plants.

[0036] In summary, this hydroponic device for zonal cultivation of plant roots, by designing the bottom support frame 1 and the top support frame 2 as extendable structures, can expand the horizontal space according to actual needs. When the number of garden plants increases in a home or agricultural production is temporarily expanded, there is no need to purchase the entire device again. The support frame can be directly extended to increase the number of cultivation boxes 3, making full use of vertical and horizontal space and effectively solving the problem of limited space utilization. At the same time, the layout of cultivation boxes 3 can be flexibly adjusted according to the space requirements of different plant growth. Furthermore, by setting up an indoor isolation layer and nutrient solution delivery pipes inside the cultivation box 3, the special environmental requirements of plants at different growth stages can be met, improving the growth quality and yield of plants.

[0037] Furthermore, by setting the fixed rod 501 in the limiting component 5, a track and limit are provided for the sliding of the movable plate 203 and the moving plate 104, ensuring that the extension and retraction process of the support frame is stable and accurate. The protruding teeth 503 on the surface of the movable plate 203 and the moving plate 104 cooperate with the limiting block 508. After the movable part slides to the appropriate position, the limiting block 508 engages with the tooth groove of the protruding teeth 503 under the action of the return spring 506, preventing it from sliding at will, ensuring the stability of the incubator 3 after placement, avoiding the incubator 3 from shaking or falling due to the movement of the support frame, and ensuring the safety and reliability of the hydroponic device.
